Global warming is already having very real consequences on our environment, as well as on all of humanity. And things are not going to get any better if very strong measures are not taken to slow the rise in temperatures.
The global rise in temperatures resulting from polluting human activity will make several parts of the world absolutely unlivable in the coming years. To determine this, NASA uses instruments present in the International Space Station (ISS), and is also developing a mission called SBG (for Surface Biology and Geology) for more information on the moisture evaporation process.
Humidity and heat
These data are essential, because they make it possible to calculate the temperature of the “wet bulb” or “wet bulb”. It is an index that measures the level from which a body or an object can cool down when moisture escapes from it. The human body is cooled by sweating when it is hot and humid. But when we fail to cool ourselves, then death awaits.
A human’s maximum resistance to withstand heat and humidity is 35 degrees Celsius for six hours, scientists say. In reality, a lot depends on physiology: in June 2021, a heat wave in the United States and Canada caused 1,400 deaths while the “wet bulb” index had not exceeded 25 degrees…
Nevertheless, this indicator can make it possible to know the dangerous regions of the world because of their prolonged episodes of extreme temperatures. This is already the case in Pakistan and the Persian Gulf, where subtropical areas have reached and exceeded 35 degrees, according to NASA observations. By adding the weather forecast models of the American space agency, several countries and geographical areas will find themselves in the same situation.
Iran, Oman, Kuwait, Egypt, Saudi Arabia, Ethiopia, Somalia, Yemen and southern Asia will be affected by this wet bulb index above 35 degrees from 2050. From 2070, it will be the turn of Brazil, part of southern Asia and eastern China which will experience it, as will several American states (Iowa, Arkansas, Missouri).
